Fig. 6: Power consumption.
a The energy/MAC required by the laser, detector, modulator, DAC, and ADC as a function of input vector size at an encoding rate of 200 MHz and assuming an ENOB of 6. b The total energy/MAC assuming an ENOB of 6 for varying encoding rates, \({f}_{0}\), using either standard fiber (i.e. relying on Rayleigh backscattering, RBS) or using enhanced Rayleigh backscattering fiber with 15 dB higher reflectance. GPU graphics processing unit, ADC analog-to-digital convert, DAC digital-to-analog converter, RBS Rayleigh backscattering, MAC multiply-accumulate, ENOB effective number of bits.
